The heat treatment tray belongs to the field of heat treatment technology and includes a first load-bearing plate and a second load-bearing plate. The first load-bearing plate is used to store tubular workpieces; Insert the second load-bearing plate into the first load-bearing plate for storing block shaped workpieces. The heat treatment material tray provided by the utility model is used for storing a second load-bearing plate for block shaped workpieces, inserted into a first load-bearing plate for storing tubular workpieces, and can store block shaped workpieces and tubular workpieces. Meanwhile, by adopting this structure, modular design of the heat treatment tray can be achieved, making it flexible to use.
